BACKGROUND OF THE INVENTION

[0004] (5.1) Field of the Invention

[0005] The present invention relates generally to telecommunications and connectivity services.

[0006] (5.2) Description of Related Art

[0007] Wireless telecommunications has become important for both business and personal use. FIG. 1A (Prior Art) illustrates an exemplary wireless communications device, a cellular radiotelephone 30 (hereinafter referred to using the common term “cellphone 30”). An antenna 31 sends and receives telecommunication signals 32. The cellphone 30 includes a memory 34 a, having programming 34 b. A transceiver 36 is provided for transmitting and receiving cellular communications signals via a base station (see FIG. 1B description below). A processor 38 controls the operations and provides an interface between other elements of the cellphone 30, namely a keypad 40, microphone 42, speaker 44, and display 45.

[0008]FIG. 1B (Prior Art) depicts a cellular telephone service system 18. There are a plurality of base stations 20A, 20B, 20C wherein each base station defines a respective cell 21A, 21B, 21C. There is at least one mobile switching center 22 connected (illustrated by straight lines) to a subscriber data base 24, a message center 26, and an activation center 27. Each of the base stations 20A-20C conforms to an industry standard (e.g., IS-56B) and sends and receives telecommunication signals (illustrated by lightning-bolt type lines) to and from the message center 26 and subscriber cellphones 30. In addition, the cellular system 18 is also preferably connected via the mobile switching center 22 with a public switched telephone network (PSTN) 28 (sometimes referred to in the art as a “land line telephone network”). Under normal operations, the system 18 provides telecommunications to and from subscriber cellphones 30 within a respective cell 20A-20C according to an industry standard such as IS-136. The system 18 supports telecommunications both between a cellphone 30 and the PSTN 28 to land line telephones or another subscriber cellphone. Note that known manner satellite telecommunications can be similarly described.

[0009] When a signal 32 between a cellphone 30 and a base station 20A, 20B, 20C fades due to distance from the base station 20A or due to signal interference by man-made structures or geographic features between the cellphone and the base station, relay towers, relay satellites, or the like, an on-going call is often cut off, or “dropped.” This results in customer frustration at both ends of the connection and perhaps added costs to re-establish communication between the parties to the dropped call. One solution has been for the cellphone service providers to credit customers who take the time to complain about a dropped call. This is overhead for all parties concerned.

BRIEF SUMMARY OF THE INVENTION

[0010] The present invention provides a value-added service and apparatus for customers who have just experienced an unexpected disconnection.

[0011] The foregoing summary is not intended to be an inclusive list of all the aspects, objects, advantages and features of the present invention nor should any limitation on the scope of the invention be implied therefrom. This Summary is provided in accordance with the mandate of 37 C.F.R. 1.73 and M.P.E.P. 608.01(d) merely to apprise the public, and more especially those interested in the particular art to which the invention relates, of the nature of the invention in order to be of assistance in aiding ready understanding of the patent in future searches.

DETAILED DESCRIPTION OF THE INVENTION

[0016] Turning also to FIG. 2, it is assumed that a cellular phone call is in progress 32. Programming 34 b for the operating system of the cellphone 30 monitors the call-in-progress 210 for the end of the call. If the call is through the PSTN 28, namely from a cellphone to a land line telephone (not shown), the cellular provider service also monitors the call-in-progress with respect to signal strength to the extent necessary to determine if a call was terminated intentionally or unintentionally due to signal fade; in other words, to determine if the call was unintentionally dropped.

[0017] If a call is normally terminated, 220, NO-path, the process is not employed, STOP 221. Whenever a call is dropped 220, YES-path, each party receives 230 a notification that the call was dropped. The notification can be in a variety of forms, for example, a pre-recorded audio message or an on-screen text message. For example, with respect to each involved cellphone 30, the drop notification is programmed into the cellphones' programming 34 b associated with the processor 38. For example, with respect to a land line phone, a connection from the PSTN 28 can be maintained by the monitoring provider service, or a related service, and the notification provided.

[0018] User options 230 are also provided. For example, a recorded message might announce, “Your call has been disconnected. Press 1 to attempt to reconnect; press 2 to send a message; or, you may simply hang-up.” The user makes a selection 240. A “HANG-UP” (see so-labeled path of the flowchart of FIG. 2) simply terminates the process 241. If the user attempts a “RECONNECT” option, the service programming will determine if signal strength is sufficient for restoring a connection. As an option, the service may predetermine if the call is potentially restorable before offering the reconnection option; an announcement regarding signal strength, range, roaming charges, and the like may be provided. The variations for these steps may be dependent upon several factors and tailored to any specific implementation. If there is the potential to restore the signal strength, 250, YES-path, (e.g., when an automobile cellphone call fades and drops a call while passing under a bridge), an attempt is made 250. If connection is not re-established, the user is again notified and given the set of options 230. As generalized examples, if the call is between a cellphone and a land line telephone, the option may be provided to both parties or solely to the cellphone user; if the call is between two cellphones, the option may be provided to one or both, preferably to the initial caller; if call blocking is involved, a callback number may not be available, and such parties may be left out of the process. Other options in accordance with the state of the art and instruments involved can be tailored to any specific implementation in accordance with proprietary software of the provider and needs of their customers. If the call 32 connection is re-established 250, YES-path, the process again monitors for the end of call 210. Note that in the state of the art, if the cellular provider is able to restore the wireless signal, then the parties may be instantly reconnected if they are both still on the line. If the cellphone user has hung up, the unit will ring just as when placing a new call. If the land line user has hung up, a re-call can be placed only if their number is known, i.e., if the cellphone user dialed the original call or else the land line caller provided caller-identification information. If unsuccessful 250, NO-path, a failure notification is provided and the process loops through the restoration/messaging subroutines 230 again. If reconnection is successful 250, YES-path, the process loops to monitoring 210 the call.

[0019] The other option given 240, “SEND MESSAGE”-path, is to allow the caller to leave an electronically recorded message 260, e.g., “press 2 to leave a voicemail.” Note that the “press 1 . . . ” and “press 2 . . . ” and the like options generally are given automatically and sequentially in a known manner. As an example of another option, a known manner electronic text message might be sent by the participant. When this option is selected, the user is given appropriate prompts, if any, e.g., “Please record your message after the tone.” and the message is recorded 260.

[0020] A check 270 is made to determine whether there is a known destination for the message. If not 270, NO-path, another notification and option 280 must be given, e.g., “Please enter a destination telephone number.” Note that for the cellphone party, if the call was an in-coming call and caller-identification information was not available (e.g., an international call), then in order to leave voice mail, the user needs to provide the destination telephone number. Otherwise, the number of the land line party should be known automatically. For the land line party, the process is being handled by the cellular provider, knowing the number of the cell phone even when a known manner caller-identification routine has call blocking; the user would need to provide a different destination telephone number if the cellphone user does not have activated voice mail.

[0021] In another option, the cellular provider may simply provide an automatic reconnect service. That is, e.g., by monitoring the signal strength and connection activity, if a call is dropped, the system simply connects the participants, ringing any participant that has hung-up following the unintentional disconnect event.

[0022] Thus, at flowchart connection 240, the user has selected one of three options to the experience of the dropped call; (1) the user can simply leave the call terminated, 240 “HANG-UP”-path; (2) attempt the reconnection, 240 “RECONNECT”-path, or (3) attempt to leave a message, 240 “SEND MESSAGE”-path. Other options may be provided in accordance with a specific implementation.

[0023] If the user selection is to send a voice mail 240, “SEND MESSAGE”-path, a prompt (e.g., “Please record after the tone”) and recording cycle is executed in a state of the art known manner. The user is again prompted for delivering the message. For a land line party, the message is delivered to the cellphone's voicemail mailbox. For the cellphone party the message is delivered to a queue of outgoing messages stored 34 a on-board the cellphone. Later, namely when signal strength is restored, the cellphone can automatically or manually initiate the transfer of the message. Preferably, the cellphone would automatically connect to the cellular service provider and deliver the message to an outbound queue of messages. This allows the cellphone to minimize its connection time, battery expenditure, and complexity of operations. The cellular service provider then delivers the queue of outbound messages via one or more outbound calling devices in a state of the art known manner. The message is then delivered 290, ending 291 the process.

[0024] In an alternative embodiment, the system and technique described hereinabove can be applied to other kinds of synchronous communication where a connection between parties can be lost, for example, text-mode chat over the Internet. In wireless Internet communication devices, a message to the user can offer to send a message to the other party when connection with that party is next restored.

[0025] Note that it is envisioned that the system and technique can be expanded and adapted by appropriate programming for conference calling between more than two parties on more than two instruments.

[0026] A provider can offer the system capability and technique described herein as a distinguishing feature of their method of doing business, optionally charging one or both parties for its use either as a subscribed regular feature or on a one-time charge.
